Home Power Magazine has many advertisers. One is SunELec.com
You can find a $15 20 amp 12 volt PWM solar controller here. AliExpress.com and search for 20A PWM solar controller. Then search for "Lowest price" in the upper section above the first post.
My suggestion is to spend more on solar panels, less on the lower cost PWM controller, and you will have a system that will recharge your battery by noon. Some might recommend a $169 MPPT solar controller. Sure it might put out about 10% more power each day than a PWM solar controller. however you can also buy a 100 watt solar panel for that same amount of money, and add to your total wattage in to the battery for less money.
